Description: This follows #23536. Also, see #23686, #23740. Add cfmakeraw(), cfmakeecho(), and cfmakecbreak(); make setraw() and setcbreak() return saved termios attributes to avoid extra tcgetattr() calls. Post #23686, #23546, #23740 goals: add test_winsize() to "Lib/test/test_pty.py"; major revision of "Lib/pty.py", which has not happened since the beginning of the millennium. Notes List of all POSIX.1-2017 input mode flags - https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html#tag_13_72_03_02. List of all POSIX.1-2017 local mode flags - https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html#tag_13_72_03_06. Naming justification for the functions: https://man7.org/linux/man-pages/man3/cfmakeraw.3.html Note that cfmakeraw() is not POSIX compliant; it is available on the BSDs and in glibc. However, POSIX has functions with similar names; for example, consider cfgetispeed(). Please see https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html. test_winch() will be resubmitted as a part of a later pull request. #23686 replaces class winsize. #23740 replaces tty.login_tty().
